SOLE-PRESSING MACHINE.

Specification of Letters Patent.

T0 aZZwhom it may concern:

Be it known that I, HENRY W'. EAs'rHAM, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Pressing Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to sole pressing machines and more particularly to machines of that class known as sole molding machines which are employed for shaping a sole before it is incorporated in the boot or shoe.

The object of the present invention is to provide certain improvements in a machine of this type for accurately positioning a sole preliminary to the pressing operation without necessitating any changes in the construction or mode of operation of the cooperating pressing forms.

l/Vith this object in view, one feature of the invention consists in the provision of a gage permanently located in a sole en gaging position with relation to the supporting form and having a sole engaging edge normally projecting above the upper surface of the solo. in the simplest and most eilicient form of the invention which has yet been devised the gage member is formed of resilient material and is provided with a curved sole engaging edge projecting above the upper surt'ace oi the sole and arranged to flatten out when the cooperating :forms are moved into pressing position while maintaining a constant lateral position with relation to the forms.

Still further features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description.

In the accompanying drawings: Figure 1 is a verticallongitudinal section of a portion oi wellknown type of solo molding machine embodying the present invention in its preferred form; Fig. 2 is a detail plan v1ew partly broken away, of the lower form carrying slide and associated gages and gripping device; Fig. 3 1s a detail illustrating Patented Nov. 1'7, 191%.

Application filed April 2, 1913. Serial No. 758,329.

a side elevation partly in section, of the construction shown in F 1g. 2; and Fig. a is a detail illustrating the side gage when the two cooperating forms are in pressing position.

The machine shown in the illustrated embodin'leut oi the invention consists of an upper :lorln 1 removably secured in the usual manner on a carrier which is supported i a stationary cross head 3 and is hell crank 1i which is mounted upon the cross-hcad T and has one arm connected to theslide ('3 by means of a link 19, the other arm oi the bell crank being conncctedby a link 13 to an arm l-Ll integral with a rock shaft 15 journaled upon the 'lrame of the machine. An arm 16 extends rcarwardly from the rock shaft 15 and is connected by a tension spring 17 to the stationary crosshead During the rising and falling movements ot' the crosshead 7 the bell crank 11 is rocl-ced and impartsinward and outward movements to the slide 6.

The heel end of the sole is positioned longitudinally oil. the lower TfOl'lll by a gage it) a d justably mounted upon the form carrying slide in the usual manner and contacting with the heel end of the sole throughout the entire pressing operation. During the lun-ixontal movementoi the form carrying slide into pressing position a gripping cleric pivotally supported upon the form carrying slide is actuated in the usual manner to clamp the heel end of the sole through a stationary roll. 22 engaging with the upper face of the gripping arm.

a In order to allow the gage and gripping devices to remain in contact with the sole during the pressing operation the heel end of the pressing form is provided with a cut-,

been only briefly described as it is substantially the same as that disclosed in the U. S. patent to Preble, No. 1,004,075, dated September 26, 1911.

In addition to gaging the position of the sole longitudinally, it is desirable to provide a simple and compact mechanism for accurately determining the relative lateral position of the sole and form. It is furthermore desirable that the gage member shall contact with and position the sole during the entire pressing operation, and that the employment of the gage member shall not necessitate any alterations in the construction or mode of operation of the forms. To this end the gage member is permanently located in a sole engaging position with relation to the supporting form and is arranged to yield upon a movement of the forms into pressing position while maintaining a constant lateral position of the sole engaging edge.

The machine shown in the illustrated embodiment of the invention is provided with a resilient arch shaped gage member 25 having its opposite ends resting upon the supporting form and arranged to yield as the supporting form moves into a pressing position until it occupies the space between the two forms equaling the thickness of the sole under pressure, as shown clearly in Fig. 4;. The sole engaging edge of the member is curved in conformity with the curvature of the sole edge, and as the gage flattens out under pressure the relative lateral position of the sole engaging edge and the forms remains constant. lVith this construction the edge of the gage member remains in contact with the sole edge throughout substantially the entire thickness of the edge during the pressing operation. The gage is conveniently supported upon the free end of an arm 27 pivotally mounted at 28 on a bracket 29 secured to the form carrying slide 6. The gage is adjusted laterally by swinging the arm :27 about its pivotal connection and is locked in any adjusted position by a stud 81 formed upon the arm which engages with one of a plurality of recesses 30 formed in the face of the bracket. The arm 27 is conveniently manipulated by a handle 32 formed upon the end of the arm.

l Vhile it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is flepiea of this patent may be obtained for not essential except so far as specified in the claims, and may be changed or modified forms to mold a sole between them, and a gage permanently located in a sole engaging position. between the pressing. surfaces of the two forms and having a sole engaging edge normally projecting above the upper surface of the sole and contacting with the sole edge throughout substantially the entire thickness.

2. A sole pressing machine having, in combination, a supporting form, a cooperating pressing form, mechanism for relatively actuating the forms to mold a sole between them, and a resilient gage permanently located upon the surface of the supporting form and arranged to yield toward the face of the supporting form when the two forms are moved into a pressing position.

3. A sole pressing machine having, in combination, a supporting form, a cooperating pressing form, mechanism for relatively actuating the forms to mold a sole between them, and a gage located upon the surface of the supporting form and having a curved sole engaging edge arranged to flatten out under pressure while maintaining a constant lateral position with relation to the forms.

4. A sole pressing machine, having, in combination, a supporting form, a cooperating pressing form, mechanism for relatively actuating the forms to mold a sole between them, and a gage contacting with the supporting form at its opposite ends and arched in the direction of the length of the form to maintain the sole engaging edge in a constant lateral position when thegage member yields under pressure.

5. A, sole pressing machine comprising a form carrying slide, a form mounted upon the slide, a gage located upon the surface of the supporting form, and a gage supporting arm fulcrumed upon the slide and having provision for angular adjustment to vary the lateral position of the gage and form.
